Mozilla can't really do their own thing unless they start writing some closed-source code. And then negotiating directly with various content providers about what the code will do. Probably a few other things I haven't thought of as well. It's all possible, but it'd be a pretty big difference from what Mozilla does normally and I'm not sure they'd be very good at it. So outsourcing that stuff makes a good bit of sense.
